Trail Connections

Public Trails: Trail Connections
The 2020-2025 King County Parks, Recreation, Trails and Open Space Levy funds a number projects across King County to expand and connect regional and public trails:
- East Lake Sammamish Trail (South Sammamish B): Design and construct an alternative, non-motorized transportation corridor and a multi-user recreational trail along 11 miles of a former Burlington Northern Santa Fe (BNSF) railroad corridor on the east side of Lake Sammamish, from Redmond to Issaquah. South Sammamish Segment B is the final 3.6-mile trail segment to be redeveloped and to expedite construction this final segment is being constructed in two phases: Phase 1 (SE 33rd Street to Mint Grove, 1.65 miles) and Phase 2 (Mint Grove to Inglewood Hill Road, 1.85 miles).
- East Lake Sammamish Tail (Downtown Redmond Light Rail Extension): Contributes to Sound Transit’s Downtown Redmond Link Extension design-build project to construct a trail approximately 1/3 mile long, including a new bridge over Bear Creek and pedestrian underpasses of the SR520 on- and off-ramps.
- Eastrail (North Phase 1 & 2 – Rail/Tie Removal & Interim Trail): This project is for the planning, design, permitting and construction of rail and tie removal (6.5 miles) of Eastrail North Segment within Kirkland and Woodinville and establishing an interim gravel trail for 2.25 miles (surfacing, signage, intersection improvements, and other improvements).
- Eastrail (SR 520 Connection, Northrup Connector): Connects the SR 520 Trail at Northup Way in Bellevue. This project supports Eastrail Partners in the development of the Northup Connector Ramp and includes the management of a potential $500,000 King County contribution.
- Eastrail (Lake Lanes): This project is a partnership with WSDOT aimed to connect the trail from WSDOT ROW across the Wilburton trestle to SE 5th in Bellevue. The full project includes oversight and management for a partnership with WSDOT constructing 2.5 miles of trail and a new bridge crossing over I-405. The levy commitment for King County Parks is the construction of the “Lake Lanes” portion only which is the trail between Ripley Lane and Coal Creek Parkway. The WSDOT portion of the project is construction within the I-405 corridor.
- Green River Trail Extension North (Seattle): Extend the Green River Trail from its current boundary at South 102nd Street in Tukwila north to 14th Avenue South in Seattle, making an important connection to the Duwamish River Trail and filling an important missing link in the Regional Trails System in an underserved area of King County.
- Green to Cedars River Trail (Maple Valley): The South Interim Trail (Segment A) of the Green to Cedar River Trail will be a 1.8 mile interim trail between SE Kent Kangley Road and the Black Diamond Open Space west parking lot.
- Lake to Sound (Section D): This project will construct the next segment of the trail east of Lake to Sound Trail Section A toward downtown Renton. This includes 1 mile from Black River Riparian Forest Park (Segment A) to Shattuck Ave. S. The commitment for the 2020-2025 King County Parks, Recreation, Trails and Open Space Levy is design only.
- Lake to Sound (Section E): This project will extend the trail east from Lake to Sound Trail Section D through downtown Renton. This includes 3/4 miles from the Cedar River Trail to Shattuck Ave. S. The commitment for the 2020-2025 King County Parks, Recreation, Trails and Open Space Levy is design only.
- Lake to Sound (Section F): This project will develop 1 mile of trail from the Green River Trail to I-5. The commitment for the 2020-2025 King County Parks, Recreation, Trails and Open Space Levy is design only.
- Soos Creek Regional Trail: A segment from SE 192nd Street to SE 186th Street with a backcountry trail connection to Boulevard Lane Park is planned for design and construction. A portion of this trail would be constructed by a developer through an agreement with King County.
Public Trails: Trail Connections (Pass-through Funding)
Pass-through funding from the 2020-2025 King County Parks, Recreation, Trails and Open Space Levy distributes levy proceeds to several cities in King County through a reimbursement process to expand and connect regional and public trails through supplemental parks property tax levy agreements:
- City of Lake Forest Park (Burke-Gilman – Interurban Trail Connection): Development of a bike and pedestrian connection between the Lake Forest Park Town Center and the Burke Gilman Trail.
- City of Shoreline (148th Street Non-Motorized Bridge Project): The 148th Street Non-Motorized Bridge Project is a pedestrian/bicycle bridge spanning I-5 in the proximity of N 148th Street. Design will include touch down areas with neighborhood connections and integrated connection to the Sound Transit Shoreline South/148th Station (light rail beginning service in 2024). This project represents an essential connection in the Off Corridor Bike Network which will link the Interurban Trail with the Burke Gilman Trail and provide access to the planned Trail Along the Rail. The bridge will also directly connect west side neighborhoods to/from the future light rail station which will in-turn connect users to local parks and schools as well regional centers of employment, commerce and education. The City of Shoreline intends to construct this Project in two separate phases. Phase 1, anticipated to begin summer of 2022 and finish by the end of 2023, will construct all improvements on the east side of Interstate 5, including new bicycle/pedestrian pathway connections to the Trail Along the Rail (TAR) and the Shoreline South/148th Station. The levy funds associated with this scope of work will be used for Phase 1 Construction only. Phase 2 will include right-of-way acquisition and construction of all improvements on the west side of Interstate 5, which will include a new bicycle/pedestrian trail connection to 1st Ave NE and the bridge superstructure itself. The timeline for Phase 2 will occur at a date to be determined.
- City of Kent (Green River Trail Missing Link): The City of Kent is working in partnership with King County Parks and King County Flood Control District on a series of projects involving the Green River Levee and Trail system, also known as the Milwaukee II Levee. The project location is the missing link of trail between the southerly intersection of the Green River Trail and Interurban Trail and the intersection of 3rd Avenue and S 259th St. The project scope will primarily consist of linking the boundary of the Green River Trail at Foster Park through the Union Pacific Railroad (UPRR) right of way to the planned sections of Green River Trail to be constructed as part of the Milwaukee II Levee project. Funding through this agreement would be utilized for three distinct phases: preliminary design and engineering, design and construction drawings, and construction.
- City of Woodinville (Greenbrier Trail): In late 2020 the City of Woodinville was made aware of serious deterioration and damage to the Greenbrier Trail located just east of the Greenbrier neighborhood. To accomplish the task of refurbishing the trail staff sought out the assistance of Washington Trails Association (WTA) to complete the trail work. Due to the amount of work involved and the availability of WTA resources this project is being split into two phases. The first phase addressing the most hazardous portion of the trail and the second phase, to take place in 2022, will address areas of lesser damage. The City of Woodinville will work with WTA to engage the local community and encourage residents to volunteer on the project. Staff may also hold community meetings to update the neighborhood on the benefits and impacts of the project. Activities include a critical areas review, completion of SEPA activities, and two phases of construction.
- City of Milton (Interurban Trail Connection): The Milton portion of the Interurban Trail ends at 380th St. in King County and then picks up again right off of Military Road just north of 31st Ave at the Edgewood city limits. This project would connect the two trailheads utilizing as much right of way and city property or WSDOT ROW as possible while still maintaining the character of the Interurban Trail. The goals of this project are to connect the two trailheads in a manner that promotes safety and mobility for both recreational and commute users and retain the character of the Interurban Trail and utilize property and infrastructure in the most efficient manner possible. Activities include analysis and public outreach, land surveying and mapping, and preliminary engineering.
- City of Kirkland (Kirkland Green Loop): The Green Loop Trail was a goal identified in Kirkland’s Finn Hill Neighborhood Plan and adopted into the City’s Comprehensive Plan in 2018. Priorities discussed in the plan are open space conservation, desired improvements to existing parks, expansion of park land, creating a Green Loop Corridor, pedestrian and bike trails, and improved access to Lake Washington. Specifically, the plan identifies the establishment of a Green Loop Corridor that circles the neighborhood connecting parks, open spaces, pedestrian trails, wildlife corridors and natural areas. Activities include acquiring parcels along Juanita Drive, completing a Green Loop Master Plan, easements and land acquisitions, trail design and final trail construction.
